'This essentiallydiifers 4from mere'jet-pipesarranged sothat the issuing airor gasA acts upon the outside body ofwater independentlyof tubes for'eoniningitluterally, and forrestraining'the escaping Aed or ujasted' inl ineffective directions, andrv'hich establish a draught or suction that favors themovement of thevessel in the direction required.'v v 4 I Referring to the :accompanyingdrawing-,1A represents the hull oi' a, b'out or vessel having'uny'number of tubes, open at their opposite'-ends,'undV {ittcd in oruboutfand through it, below the-watergli'ne, say tubesa, run ning fromthe bow backwurdly, nmlopen :it their rear crnds to or'through-the sidesor bottom of theb'oat, arid other tubes, b, running clear uthwart thevessel, near Aboth bow und stern, or either, also, it may be tubes e,urrnngedoutside the hull, es,`for instance, along either side ofthekeel.

Forpropulsiou ormovement of the vessel in a. l'orwerd directiii, the orifices c in thejet-pipes d tQ the tubes a and c, should face in a. backward direction,

'To steer or turn the vessel in o osito directions, the i es cl in thetubes b ma' be made ca ame of turnincf so PP P P .7 P a as to reversethe position of the orifices e, from facing right to facing left, orvice versa.' The arrangement of lthe tubes a in or through the frontportion ofthe boat or vessel, contributes to diminish bow or forwardresist-A ance in sailing.

Though not restricting the invention to the employment of any partieulurgas or air, or mode of generating or producing the same, it will heresulice to say that the pipes cl are shown in the drawing asiderivingtheir supply of' compressed air from reservoirs R, which may have thefluid forced into them by a motor or powergenerator, consisting of afree piston working in a cylinder, S, lay-gaseous explosion, to give itstart-ing-imp'e'tilsa but which power-generator it is unnecessary hereto rrr/ore minutely describe, as the same forms the subject 'of aseparate pending application for patent, and the necessary power may beotherwise produced.

What is here claimed, and desired to be, secured by Letters Patent, is

The combination of the tubes c b, open at both ends with the jet-tubesd,arranged to project Within the l former intermedintely of their length,and with theirjet-orifices facing either open end of 'said larger tubes,sub'- stantially as shown and described.
